Making And Receiving Secure Calls; Tracing Suspicious Calls - Cisco 7970 Series Phone Manual

Making and Receiving Secure Calls

Depending on how your system administrator has configured your phone system, your phone might
support making and receiving secure calls.
Your phone is capable of supporting these types of calls:
• Authenticated call—The identities of all phones participating in the call have been verified.
• Encrypted call—The phone is receiving and transmitting encrypted audio (your conversation)
within the Cisco IP network. Encrypted calls are also authenticated.
• Non-secure call—At least one of the participating phones or the connection does not support these
security features, or the phones cannot be verified.

Tracing Suspicious Calls

If you are receiving suspicious or malicious calls, your system administrator can add the Malicious Call
Identification (MCID) feature to your phone. This feature enables you to identify an active call as
suspicious, which initiates a series of automated tracking and notification messages.

Look for a security icon in the top right corner of the call
activity area, next to the call duration timer:

Encrypted call
Neither security icon appears if the call is non-secure.
Contact your system administrator.
Then...
Press MCID.
Your phone plays a tone and displays the message, "MCID successful."
